EPC Benefits
• Replaces old equipment with modern state of the art energy efficient technology
• Replaces old pneumatic technology with DDC control systems
• Systems integration through energy management technology
• Provides funding steam for larger capital projects
EPC Contributions
• 30% reduction in projected energy costs
• More than $8M in utility cost savings to date
• 41,368 metric tons of carbon emissions offset, the equivalent to removing 8,858 cars from the road for a year
• LEED-EB of five buildings
• 1st State Capitol Building in the nation to be LEED certified
Larger Capital Projects
• DPA Funding Request demonstrates combination of EPC, CM, CC and COP’s for building renovation
What Motivated DPA to pursue multi-phase EPC’s
• seeing the performance of the project with guarantees.
• EPC provides less risk as contract costs are locked in and performance of the system backed by the guarantee so savings persist.
• ‘low-hanging’ fruit in phase I LIGHTING produced quick energy savings during guarantee 3 year period.
• Excess savings from Phase I and Phase II helped fund phase III.
• PV Xcel had good incentives that were leveraged and rebates of course in each phase.
